Process for producing aromatic polyester polycarbonate particles |
(57) A process for producing aromatic polyester polycarbonate particles from a methylene
chloride solution of an aromatic polyester polycarbonate comprises continuously supplying
the methylene chloride solution of an aromatic polyester polycarbonate to a particle-forming
tank, heating it while maintaining it in a suspended state in water to evaporate methylene
chloride and to form aromatic polyester polycarbonate particles, subjecting at least
a part of the resulting aqueous slurry withdrawn from the particle-forming tank and
containing the aromatic polyester polycarbonate particles to wet pulverization treatment
and recycling the treated slurry to the particle-forming tank.
